Serial No. 416,459.

To all whom it may concern:

I to which switch points a bar 3 is connected,

Be it known that 1, JOHN H. JACKSON, a which is reciprocal within bearings 4, which citizen of the United States, residing at Watonga, in the county of Blaine and State of Oklahoma, have invented a new and useful Electric Switch-Register; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a new and useful switch or block signal system or an elec tric switch register; and the invention in its broadest aspect resides particularly and especially in a device for indicating to or notifying the ofiicials in an office, signal station or tower, depot, or other building, the condition or position of a railroad switch.

This invention comprises further objects and combinations of elements, which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

The features, elements and the arrangement thereof, which constitute the above entitled invention, may be changed and varied, that is to say, in an actual reduction to practice, with the understanding that the changes and variations accruing from said reduction to practice are limited to the scope of the appended claims.

To obtain a full and correct understanding, of the details of construction, combinations of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accompanying drawings in connection therewith, wherein,

Figure 1 is a perspective view of a portion of a railway, embodying the switch mechanism, and a signal station, which station is shown in elevation. Fig. 2 is a cross sectional view taken through the metal inclosure, adapted to hold the push button. Fig. 3 is a detail perspective view of the switch bar, and its upwardly extending arm havin the lateral projection. Fig. 4 1s a sectiona view on line 44 of Fig. 3, clearly illustrating the construction of the upwardly ex tending arm, with relation to the switch bar.

In regard to the drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures, 1 designates the main rails of a railroad, and 2 indicates the switch points of the side track,

are secured to the ties 5 and 6 of the railroad,

as clearly shown; this bar 3 operates in any conventional manner a switch indicator, which indicates whether'the switch is open or closed. The switch bar is operated by a suitable lever 7, which is provided with a spring actuated pawl or dog 8, designed to engage teeth of a quadrant 10, for the purpose of holding the lever in adjusted positions.

Mounted upon the ties 5 and 6 is a metal inclosure 11, made preferably of iron, and is provided with two compartments 1 2 and 1 3, in one of which a push button 14 is fixed, which push button is cooperated with by means of a lateral projection 15, of the arm 16, the lower end of which is bifurcated, as shown at 17, to fit the switch bar 3, as clearly shown in Fig. 3; 18 designates a bolt which passes through apertures 19 and 20 of the bifurcated end of the arm and the switch bar, and to the threaded end of said bolt a nut 21 is connected, for the purpose of securely mounting the arm of the switch bar. The lateral projections of the arm operates through an aperture 22 of the inclosure, and is provided with a rubber tip 23 to contact with the push button. The push button, as will be observed, is of the usual type, therefore it is not necessary to enter into the detail construction thereof, which is foreign to the present invention.

The inclosure is provided with a hinged closure 24, which is provided with a suitable clasp 25, adapted to engage the staple 26, after which a suitable padlock of any conventional form is connected to said staple for the purpose of securely locking the closure.

27 indicates a signaling station, in which an electrical alarm bell 28 is fixed, as clearly shown; there may be a plurality of bells mounted therein, that is to say, when there is a plurality of switches. The electrical alarm bell is of the usual form having the usual magnets and armature, and is provided with a pair of binding posts 29, to which wires 30 and 31 are connected, the wire 31 being connected to a battery, while the wire 30 is connected to the push button, as will be clearly manifest. Extending from the battery to the push button is a wire 32, as clearly shown, and when the switch bar is operated by the lever 7, so as to cause the lateral projections to engage said push button, an electric circuit is completed, which will cause the electrical alarm bell to notify the officials in the signaling station that the switch is open, as

will be clearly evident.

In an endeavor to ascertain the operation of the above set forth device, it will be clearly seen that when the switch is open the bell will ring and when the switch is closed the bell will cease to ring, the normal position of the switch being closed.

From the foregoing, the essential features, elements and the operation of the device, together with the simplicity thereof will be clearly apparent.

, Having thus fully described the invention,v

what is claimed as new and useful, by the protection of Letters-Patent, is

1. In a device as set forth, a pair of switch points, a reciprocal switch bar connected thereto and provided with an arm having a bifurcated end to fit said switch bar, said arm having a projection, a bolt and nut to fasten the arm to the switch bar, a push button, an inclosure therefor having an aperture through which said projection operates to engage the push button and provided with a hinged closure, an electrical bell in circuit with said push button, and a lever to operate said switch bar, so as to cause the projection to engage said push button.

2. In a device as set forth, a pair of switch points, a reciprocal switch bar connected thereto and provided with an inverted L- shaped arm, consisting of a bifurcated portion to fit the switch bar and a projection, a push button, an inclosure therefor having an aperture through which said projection operates to engage the push button, and an electrical bell in circuit with said push button.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
